The H20 is a stereo power amplifier from Hegel, built with an exceptionally high damping factor and efficient power consumption. Hegel is a Norwegian manufacturer with a serious reputation for measurement-focused amplifier engineering, and the H20 represents a substantial expression of that broader house philosophy.

Position in line

It sits below the H30A in Hegel's power amplifier hierarchy. This positioning below the H30A suggests the H20 offers capable core engineering at a somewhat more accessible tier than the brand's higher-output model.

Key specs that matter

Input impedance is 10,000 ohms balanced and 50,000 ohms single-ended. Rated output is 200 W into 8 ohms. Signal-to-noise exceeds 100 dB with distortion under 0.006% at full feedback. Maximum power consumption is a modest 60 W, suggesting an efficient amplifier design rather than a conventional heavy linear topology. Damping factor exceeds 1000, an exceptionally high figure. At 145 x 430 x 370 mm and 18 kg it is a substantial chassis.

Sound and use context

Expect an extremely controlled, high-damping-factor presentation with efficient power consumption - Hegel's characteristic engineering approach favours both strong measured performance and practical efficiency, a combination the modest 60 W maximum consumption figure reflects clearly relative to the amplifier's considerable 200 W output.

Pairing

The 10,000 ohm balanced input impedance works with any modern preamplifier without gain-matching concerns, and the exceptionally high damping factor suits demanding loudspeaker loads particularly well.

Alternatives

Hegel's H30A sits above this model with more output, worth the further investment if this model's already substantial 200 W figure and exceptional control still leave ambitions for Hegel's higher-tier power amplifier. Hegel extensive dealer network across most major markets makes arranging a proper demonstration practical for most buyers considering this substantial amplifier. A dealer demonstration comparing this model directly against the higher-tier H30A helps clarify exactly how much additional output that flagship model buys for a specific system, and a rigid, well-supported equipment shelf remains worthwhile given this chassis considerable weight. A dealer visit remains the simplest way to compare current pricing across Hegel amplifier lineup.
